On top of working on the format of the show to improve ratings, sources are saying that judge Jessie J is definitely leaving and Sir Tom Jones might follow!

Back in June we heard Jessie got a nice little big bonus to sign up for the second season of the reality competition, but now she reportedly quit because of a scheduling conflict with her upcoming tour.

While that's the official explanation, insiders say she simply angered executives with diva-esque behavior which included a refusal to do publicity along with toting around a hefty entourage.

Sir Tom Jones may be following suit as sources are also reporting that his manager is advising against taking part in another season. Here is what the winning mentor from last season had to say on a talk show recently:

"I think I will do another series. We are talking about it now. But there are a couple of things that need to be ironed out. One of the things I said I need to know is who the other coaches are, because I don’t want to be sitting there with somebody that I don’t admire or particularly like… there are a few of them! Hopefully, we will have the same four coaches."

"My metabolism actually changed like crazy this year. I have Hashimoto's disease. It's a thyroid disease, and it's now been two years since taking the medication for it, so for the VS show I didn't want to lose any more weight, I just want to have muscles in the right place, and if my butt can get a little perkier, then that's good."
